These volumes concern the local politics of Ross and Cromarty and Sutherland, the claims of the Earl of Sutherland on account of his exertions in opposing the Rebels, the means by which Sir John Gordon of Invergordon obtained the place of Secretary to the Principality, many documents concerning the Principality and Crown rents, and other matters apparently suggested to the writer by his connexion with Sir John Gordon.

In both volumes, mixed up with private or local & electioneering business, is a great mass of valuable historical and statistical information concerning the North of Scotland during the Rebellion in 1745 and for a few years after.

The description of the manuscript in the folio catalogue (F.R.186) includes the reference: Jac.v.6.32-33.
